PAIL EXTINGUISHER.

To all whom it may concern: v

Be it known that I, ORLANDO R. ERWIN, a citizen of the United States, and resident of Forest Hills, in the county of Queens and State'of New York, have invented certain new and useful Improvements in Pail EX- tinguishers, of which the following is a specification.

This invention relates to improvements in a fire extinguishing device, and more particularly to an apparatus designed for use in connection with extinguishing of'fires by manual manipulation of a vessel carrying the component solution of an extinguishing medium, and has special reference to an improved fire extinguishing vessel of the type described in the patent to Meigs, N0.-1,287,- 388 of December 10, 1918. i

In the type of fire extinguishing device described in the patent referred to, useis made of two concentrically mounted recep tacles, both open at one end,-the receptacles defining an inner central compartment and an outer annular compartment, the said compartments holding respectively an acid and a basic solution, these comprising component solutions which are adapted to be commixed in the event of fire to produce a fire extinguishing foam, thecommixture being effected by dashing the solutions through the open ends of the receptacles and towards the fire to be extinguished.- In this fire extinguishing device the inner receptacle comprises a container made of copper which is tinned. to withstand the corroding effect of the acid solution held by the container, the

receptacles being held in fixed relative positionsby means of threaded members formed in the bottoms thereof. g

It has been found that the cost of producing a fire extinguishing device of the type, referred to is relatively large, due principally to the cost of manufacturing the inner receptacle; the sheet copper of which such receptacle is made being rela tively expensiveand the cost of'making a receptacle therefrom having a bottomiprovided with a threaded female member, the whole undergoing further tinning treatment to produce a non-corroding container, being relatively high, this large production cost preventing the extensive adoption of this type of extinguisher consistent with its established and well recognized. u ility. It

has been further found that this expensive tinned copper containercould be effectively replaced by an ordinary glass 1&1, means being supplied to removably retain the glass jar in the outer receptacle, the glass jar more effectively functioning to withstand corrosive action of the acid and reducing fraction of its previous costs,

the cost of production of the device to a I The principal objects of my present iii-- vention therefore involve, in addition to the provision of an improved fire extinguishing device of the nature referred to,"having in view the production of a simple, a more efiicient. and more inexpensive vesselthe' provision of an inner container to replace the expensive metallic innercontainer used prior to my invention; the provision of such inner container which willimore efiectively Withstand corrosive-action of the acid solution contained therein; and the further provision of improvedand easily assembled means for r'em'ovablyretaining. the-inner container within the outer receptacle.

To the accomplishment" of the foregoing and such other objects as may hereinafter appear, my invention consists in the elements and" their relation-one to the other, as hereinafter particularly described and soughtto be defined in the claims, reference being had to the accompanying drawing which shows a preferred embodiment of my invention and in Which Figure l is a crosssectional 'elevational View of'the fire extinguishing device, and Figure 2 is a planview: thereof.

spect to the outer container and being m nted shqwn. the figures and: e-1,

' 9O Referring to the drawing, the outer contamer comprises preferably a tapered body ceived by the annular bead 8, this bead preventing any radial motions of the inner container with respect to the outer container.

For the purpose of more effectively withstanding the corrosive action of the acid solution held by the inner container and for the further purpose of producing a more inexpensive vessel and doing away with the tinned copper container of the patent to Meigs, the receptacle 9 of my invention comprises a vitreous container and more particularly an ordinary glass jar. This jar may be produced at a very low cost as is well known and the use of such ain this fire entinguishing vessel reduces the production and therefore the selling cost to a fraction of its previous cost.

For the purpose of retaining the glass jar 9 within the outer container and for preventing any radial or axial motion of the glass jar with respect to the outer container, simple means is provided which may consist of astrip of metal 10 bent on an intermediate portionthereof to provide opposed ,V-shaped portions 11 adapted to be mounted over opposed portions of the side walls of the container 9, the interengagement of the crook of the Vand the rim of the container 9 permitting a relative rotation of the strip of metal 10 with respect to the inner container 9, the crook of the V riding on the rim of the container during such relative rotation. Strip 10 is provided at its outer ends with upturned portions 12, these upturned portions being adapted to be received by straps 18 fitted to the inner surface of the outer container at opposed sides thereof, these straps being secured to the container by means, for example, of rivets 1 1, these rivets also serving the purpose of securing the bail clips 15 to the outer sur face of the outer container at opposed ends thereof. The strip 10 may be made of any desired material, preferably of metal, which will be effective to retain the inner container 9 in position and which will permit a resiliency of the outer portions of the strip so that the outer portions may be bent downwardly when the parts of the device are to be assembled or disassembled, the downward motion of the ends of this strip permitting the upturned portions 12 to be removed from the retaining straps 18, the strip 11 being then rotated and removed from the vessel, thereby permitting the removal of the inner container 9 from the outer receptacle 5. The vessel is provided with the usual bail 16 and with the usual cover (not shown).

The manner of assembly of the parts and use and operation of the device will be ap parent from the above description thereof. In assembling the parts, the outer container 5 may first be supplied with the B or basic 'guishing medium.

solution and the inner container 9 holding the A or acid solution may then be inserted in the outer container; the bottom of the inner container being received by the struck up annular seat 8. The strip 10 is then inserted with the V portions 11 fitting over the rim of the inner container and with the upturned portions 12 out of alineinont with the openings provided by the straps 13. The outer portions of the strip are then urged downwardly, the strip being then rotated on the glass jar until the upturned portions 12 are in alinement with the opening provided by the straps 18. Release .of pressure on the outer portions of the strip permits the upturned portions 12 to enter the said openings as will be obvious; further upward motion of the strip being prevented by the engagement of the strip with the front wall of the strap and circumferential motion of the said strip being also prevented by the confinement of the upturned portion 12 by the side walls of the said strap 13. lt will be obvious that this simple means not only secures the inner container in post tion relatively to the outer container during ordinary storage use, but permits the confinement of the inner container during operation of the vessel as a fire extinguishing device. In the event of fire, the vessel is grasped in the ordinary way and the component solutions held by the inner and outer containers respectively are dashed on to the fire, commiXture of the solutions taking place during the passage thereof from the open. ends of the containers to the point of application, namely the fire, this commixture resulting in the generation of the fire extinguishing foam which acts as a fire extin- When renewal of the charge is necessary, as, for example, when deterioration of the solutions effected by time results, or' when cleaning of the vessel is desired, the parts may be disassembled in a simple manner, the end portions of the strap being urged downwardly and the strap rotated until the upturned portions 12 are out of alinement with the straps, the strip 10 being then removed, permitting the removal of the inner container 9 by a simple upward movement of the said container 9.

It will be apparent from the above that I have provided an improved fire extinguishing device of the manually manipulable vecsel type which will reduce the vending cost to a minimum to permit more extensive use of thistype of fire extinguishing means, providing at the same time a vessel which will withstand the corrosive action of the solutions employed; providing furthermore, parts which may be easily manufactured and which may be assembled in a very facile manner.

While I have shown my device in the preferred form, it will be obvious that many means for supporting the inner receptacle in said outer receptacle comprising provisions having attachment to said outer receptacle and having means for engaging the rim of the inner receptacle, the construction of the receptacles being such that the component solutions may be simultaneously projected from the pail by a manual dashing or dumping action whereby to cause said components to intermix after'leaving the pail and produce the fire extinguishing agent.
